Substrate materials for transparent moldings injection

Polycarbonate with p-tert-butylphenol as a terminal group as substrate material, obtainable segunel procedure continuous interface by reaction of bisphenols and phosgene, being used phosgene unexceso from 8 to 17 mol% relative to the sum of the bisphenols used, wherein lasuperficie one piece molding are present corresponding intervals loads potential -1.5 to + 1.5 kV, the proportion of the total surface area is between 95 and EL100%, and are present depotencial intervals between -1.5 and +1.5 +2.5 -2.5 or whose proportion is from 0 to 5%, and are present depotencial intervals +2.5 kV whose proportion amounts to 1% of the total area of ​​the disc, wherein lamedida potential is carried out by a sonda Monroe at a distance of 3.5 mm from the surface delsustrato, ascending exploration region respectively 12 cm X and Y direction, and measured elpotencia l in steps of 2 mm in each direction X and Y direction
